The Trump Administration sought to undermine the Federal Service Labor-Management Relations Act (“the FSLMRS”) by issuing executive orders that:
[Placed] limits on the activities that federal employees may engage in when acting as labor representatives; guide[d] agencies toward particular negotiating positions during the collective bargaining process; and address[ed] the approaches agencies shall follow when disciplining or evaluating employees working within the civil service.
"Enjoin" seems to be one of those words like "sanction" or "table" with two diametrically opposite meanings. Since both sets are well entrenched in their respective linguistic communities, the best course is just to avoid them if at all possible.
