The applicant union sought certification for a bargaining unit consisting of cleaners and maintenance workers at a shopping mall, or alternatively, a unit including security guards.
The responding employer argued for an all-employee unit, citing its integrated customer service approach and the regular interchange of duties among staff.
The Board applied the community of interest test and found that while the maintenance group could likely bargain together viably, a separate unit would cause serious labour relations problems due to fragmentation.
The Board concluded that the applicant's proposed unit was not appropriate and that the employer's proposed all-employee unit was appropriate.
A representation vote was ordered for the wider unit.
