Can we draw the following hypothesis from the context? 

Context:

When the Corporation makes a decision to significantly reduce operations at a given location, there will be no layoffs, terminations or salary reductions for STRF and NABET employees who were on strength as of December 31, 1983 and who are still employed on the date of signature of this collective agreement, provided they have completed their probationary period.

Hypothesis: STRF and NABET employees cannot be laid off for any reason 
It's impossible to say
