Samwu protest in cape town
Samwu suspends CT strike
Municipal workers downed tools at the beginning of last month due to several issues.
Wage increases between Samwu and Imatu with Salga were abandoned on Tuesday.
The parties failed to find middle ground in two rounds of negotiations and hope a solution will be found.
Samwu suspended its industrial action after three days following the formation of a task team.
Some protesters looted stalls of informal traders and tipped over rubbish bins.
Samwu is leading a strike over unresolved grievances, some relating to apparent unfair dismissals.
Among the unions' concerns is the treatment of pregnant firefighters and wages for standby staff.
The union is up in arms over a number of issues including safety concerns.
The union claims line managers often victimise municipal workers.
