This case comes to us on petition to transfer from the Appellate Court under Acts 1933, ch. 151, §1, p. 800, being §4-215, Burns’ 1946 Replacement. See: Achenbach v. Review Board of Ind. Emp. See. Div. (1961), 172 N. E. 2d 214, for opinion of the Appellate Court.
The proceeding here was instituted before the Review Board of Indiana Employment Security Division to determine the eligibility of claimant-appellant, Aehenbaeh, and others, for benefits under the Indiana Employment Security Act.1
International Harvester Company operates two plants in the City of Fort Wayne, Indiana, one known as the Fort Wayne Works, and the other as the Motor Truck Engineer Division. They are located on separate premises across the street from each other.
On November 13, 1958, the UAW-CIO, Local 57, representing the production workers, and the UAW-CIO, Local 305, representing the office and clerical workers, called a strike at both plants.
Claimants-appellants, and others represented by them, who were members of Local 80 of International Die Sinkers, and Local 1608 of the International Brotherhood of Electrical Workers who worked at the Fort Wayne Works, and those who were members of Local 137 of American Federation of Technical Engineers and worked at the Motor Truck Engineer Division, *658were not on strike. Members of the first two of these non-striking unions did not cross the picket lines although work was at all times available to each and all of them.
Within the required time these workers belonging to the two non-striking unions whose members refused to cross the picket lines, filed their applications for benefits with the Indiana Employment Security Division stating that they were unemployed because of a labor dispute.
The claims of several applicants for benefits were heard before a referee on March 12, 1959. The referee found that claimants who were members of Local 80 of the International Die Sinkers Conference, Local 137 of the American Federation of Technical Engineers AFL-CIO, and Local 1608 of the International Brotherhood of Electrical Workers, AFL-CIO, were entitled to benefit rights during all of the calendar weeks covered by the duration of the strike.2
Appellee, International Harvester Company, appealed this ruling to the Eeview Board of the Indiana Employment Security Division which, after notice and hearing, issued its decision on September 2, 1959. The pertinent parts of such decision are as follows :
“FINDINGS AND CONCLUSIONS: The Board finds that a stoppage of work existed because of a labor dispute at the employer’s establishment during the period from November 13, 1958, to January 19, 1959, and that the unemployment of the claimants during such period was because of the labor dispute.
*659“The Board further finds that the claimants herein, being members of certain unions, refused to cross_ or attempt to cross picket lines formed by striking employees who were members of another union at each of the employer’s two plants in the city of Fort Wayne, Indiana.
“It is further found that said claimants refused to attempt to return to work during the period from November 13, 1958, to January 19, 1959, and that there was work available for each of said claimants during said period of time.
“It is further found that the claimants never requested any protection for the purpose of proceeding through the picket line although the city police were present for the purpose of directing traffic, nor did they seek the aid of the courts for injunctive relief from interference, if any existed, with their right to return to work had they so desired.
“It is further concluded that the claimants were participating in the labor dispute which caused their unemployment by reason of their election to honor the picket line of striking employees and their refusal to make a reasonable attempt to cross said picket line.
“It is further concluded that the evidence is insufficient to bear out the claimants’ contention that they would receive bodily harm if an attempt was made to cross the picket line.
“Therefore, it is finally concluded that the claimants, and each of them involved herein, were ineligible for unemployment benefit rights during the weeks in which they were unemployed in the period of November 13, 1958, to January 19, 1959.”
From the decision of the Review Board an appeal was prosecuted to the Appellate Court.
The sole error assigned is that the decision of the Review Board of the Indiana Employment Security Division is contrary to law.
*660The decision of the Review Board as to all questions of fact is conclusive3 and binding upon the court, and the court will not disturb the decision of the Board unless reasonable men would be bound to reach a different conclusion on the evidence in the record. Adams et al. v. Rev. Bd. Ind. Emp. Sec. Div. et al. (1957), 237 Ind. 63, 69, 143 N. E. 2d 564; Board of Medical Registration v. Armington (1961), 242 Ind. 436, 178 N. E. 2d 741; National Furniture Mfg. Co. v. Review Bd. of Ind. E. S. D. (1960), 131 Ind. App. 260, 170 N. E. 2d 381, 384.
The evidence most favorable to the decision of the Review Board may be summarized as follows:
Two unions, neither of which appellants, nor any persons represented by them, were members, were on strike at both Fort Wayne plants of appellee, International Harvester Company, from November 13, 1958, to January 19, 1959. The strike continued at the Fort Wayne Works from November 13, 1958, to January 19, 1959, and at the Motor Truck Engineer Division from November 13, 1958, to November 25, 1958. The strike resulted from a dispute involving wages and working conditions of members of the striking unions.
“Management employees” and “excluded employees” were employed at both plants and continued to work during the period of the strike, crossing picket lines each day to go to and from their work. Most of these employees carried nothing to identify them as belonging to the “management” or “excluded” group of employees.
There was a common entrance for all employees at each plant.
*661When appellants, Achenbaeh, Sills, and other members of International Die Sinkers, Local 80, and members of the International Brotherhood of Electrical Workers, Local 1608, reported to work on November 13, 1958, the first day of the strike, there were pickets at the entrance of both plants.
There is conflict in the evidence concerning the number of pickets on duty at any one time. The Industrial Relations Manager of the Motor Truck Engineer Division testified that there were 15 to 20 pickets at the entrance of that plant. Witnesses for the American Federation of Technical Engineers, Local 137, AFL-CIO, testified that “at times” there were 150 to 200 pickets at the entrance of the engineering plant, for “two or three days” and this was “probably five times” the number at both entrances to the other plant. Two other witnesses for the claimants-appellants testified that the number of pickets decreased after the first day of the strike, and at one time there were only two pickets.
The picketing was, at all times, peaceful. There is no evidence of any violence or threats of violence at either plant during the strike. No pickets were observed carrying weapons of any kind. There were women on the picket line, and at times there were more women than men at the Fort Wayne Works.
A Mr. Sills, who was president of International Die Sinkers, Local 80, and a witness for claimants-appellants, testified that when he and his men approached the picket line on the first shift on the first day of the strike he asked the picket captain if they could cross the line, and the captain replied, “No . . . he wasn’t allowing nobody to cross.” There is no evidence that this witness or any of the claimants on *662any shift insisted upon his right to enter the plant,4 nor is there any evidence that anyone made any effort to secure the aid of police, deputy sheriffs or plant guards, who were present, in enforcing their right to enter the plant.
The undisputed evidence shows that no reply was made to the picket captain when he said he wasn’t allowing anybody through the line. The witness, Mr. Sills, testified, however, that he then turned and walked back across the street where he “waited a while to see if anybody crossed.” He saw no one cross and “after a while, the fellows begin to go their ways . . . and it all thinned out”, then he went home.
Mr. Sills returned three times the first day when the other shifts were to report and informed the men on each shift that a “strike was on and they wouldn’t let us cross the picket line in the morning” and told them to “approach the picket line and see if they could get through.”
At each shift, on the first day of the strike, the men were told that they could not cross the picket line and on each occasion they left without making any further effort to cross. The president of the union, Mr. Sills, visited the plant “about 7 times” after the first day and asked someone in the picket line if he could go to work and was refused.5 Sills was never threatened with injury if he attempted to cross the picket line, nor did he ask any police officer, plant guard or plant representative to assist him, or the *663members of his union, to cross the picket line so they might get to the work which was available to them.
Officers of appellants’ unions made no effort prior to the strike to work out an agreement whereby the members of these non-striking unions would be permitted to enter the plants and perform their customary duties. Nor is there any evidence that any members of appellants’ unions ever sought from officials of the striking unions permission to cross the picket lines to go to and from their work, and no effort was ever made to work out such an arrangement except one telephone call by Mr. Sills to the president of the striking union asking him “conditions” and if they were going to “allow anybody through.” To this question the president answered, “No.”
American Federation of Technical Engineers, Local 137, AFL-CIO, were also refused permission to cross the picket line at the Motor Truck Engineer Division on November 13, 1958. However, the president of this Local, through efforts of their International Headquarters, worked out an arrangement with the striking Locals 57 and 305 whereby members of Local 137 were permitted to cross the picket lines and return to work on November 25,1958.
All managerial employees were at work on the second day of the strike, and all excluded employees on the sixth day.
The only reason given by claimants-appellants for the failure to do more than merely ask permission to cross the picket line was that they thought that the pickets would resort to physical restraint resulting in bodily injury.
We find no evidence in the record to support any fear of bodily harm resulting from an attempt to cross *664the picket lines. In fact, there is evidence that some workers, on the first day of the strike, drove their cars through the picket line and into the parking lots without any physical resistance or threats of injury from the pickets.
In our judgment there is substantial evidence to sustain the finding and conclusions of the Review Board.
Although there was evidence that some members of appellants’ unions stayed away from work because of fear of physical injury if they crossed the picket line, the Review Board was justified in considering that such fear was not real or genuine in view of the undisputed fact that the picket lines were maintained at all times in a peaceful manner and the engineers, managerial and ungraded employees who crossed the lines every day were not molested or threatened with violence.
It is not necessary that any of appellants should have experienced actual violence or bodily harm in attempting to cross the picket lines, but their fear, in light of all the circumstances must have been reasonable and genuine. The fear of violence must be real and not nebulous or imaginary. Abshier v. Review Bd., Emp. Sec. Div. (1952), 122 Ind. App. 425, 431, 105 N. E. 2d 902.
A mere verbal refusal by the pickets under the circumstances here is not sufficient to excuse claimants-appellants from crossing the picket lines. They had the legal right to do so but none of them made any attempt to enforce his right, to cross the picket lines, further than to ask permission to do so. As has been hereinabove stated, the picketing was peaceful, and there was no violence or threats of violence. *665The Review Board could have properly inferred from these facts that claimants-appellants had no real reason to fear bodily harm if they crossed the picket lines, but such fear, if any, was only imaginary and nebulous. Meyer v. Industrial Commission of Missouri (1949), 240 Mo. App. 1022, 223 S. W. 2d 835, 840.
The voluntary refusal of claimants-appellants to cross picket lines maintained by members of a union to which they do not belong makes them participants in the labor dispute involved. American Brake Shoe Co. v. Annunzio (1950), 405 Ill. 44, 90 N. E. 2d 83, 85, 86; Baldassaris v. Egan (1949), 135 Conn. 695, 68 A. 2d 120, 122.
Voluntary, under such circumstances, includes belief in union concepts and tenets; acquiesence in superior union officers’ advice; and actions in concert and support of a striking union.
Involuntary includes actual violence, or the threat of violence, or apparent observation of circumstances at the picket line or elsewhere which would induce a reasonable and genuine belief of violence occurring if a crossing was attempted.
As stated by the Supreme Court of Washington In re St. Paul & Tacoma Lumber Co. (1941), 7 Wn. 2d 580, 595, 110 P. 2d 877, 884, “It is obvious that such a refusal does constitute participation, since, by so refusing to work, the persons are adding their strength to the cause of the strikers, who are then put in a better bargaining position when the entire plant is shut down than when their branch of it has stopped only a portion of the operations.”
*666*665The mere fact that the passage through the picket lines might have been contrary to claimants-appel*666lants’ union convictions and beliefs was not sufficient “to make their refusal involuntary, since they had a legal right to pass the lines if they so desired.” In re St. Paul & Tacoma Lumber Co., supra, at page 595 of 7 Wn. 2d, page 884 of 110 P. 2d.
As was so aptly stated in Bodinson Mfg. Co. v. California Employment Commission (1941), 17 Cal. 2d 321, 109 P. 2d 935, at page 940, the claimants-appellants here “were unemployed solely because, in accordance with their union principles, they did not choose to work in a plant where certain of their fellow employees were on strike. Their own consciences and iaith in their union principles dictated their action. This choice is one which members of organized labor are frequently called upon to make, and in the eyes of the law this kind of choice has never been deemed involuntary.”
Voluntary unemployment is not compensable under the purpose of the Act, which is to provide benefits for persons unemployed through no fault of their own. Abshier v. Review Bd., Emp. Sec. Div., supra (1952), 122 Ind. App. 425, 430, 105 N. E. 2d 902.
The Review Board correctly concluded that claimants-appellants were participants in a labor dispute which caused their unemployment and that because of this fact they were ineligible for unemployment benefit rights during the period of the strike.
