ON PETITION FOR REHEARING.
PER CURIAM.Respondent’s petition for rehearing makes the point that the Board’s order, which we ordered enforced, was to some extent predicated upon a continuing contract basis which we rejected. This matter we had already considered. Perhaps, however, we should make clear that we do not read the Board’s opinion to require any particular measure of back pay, which is a subject for later proceedings, nor does reinstatement preclude collective bargaining about pay and the status of the reinstated employees.
The petition for rehearing is denied.
