The UATUC denounces the common practice among employers to unilaterally change working conditions for workers who are members of a union to put pressure on and harass them. It is frequent that a worker who has become a union representative will get less advancement opportunities. Workers are often discouraged from joining the union and often threatened with the non-renewal of their contract. Sometimes they are even offered money to leave the union, especially in sectors with a particularly vulnerable workforce, like the retail sector. Other cases of antiunion discrimination include overtime work and limiting the right to leave; threats of dismissal; contracts offered with less favourable terms, including lower pay; distribution of working time changed; changes in location of work (that is that workers are sent to remote places, where shop stewards cannot establish contact with union members).
The real scope of the problem is hard to objectively assess due to underreporting and difficulties in proving (direct) discrimination on such grounds.
