Vodafone Ghana Call centre operators at the High Street branch have declared an indefinite strike Monday over poor working conditions and low salaries.Employees of the centre are angry over what they say is their mother company, TeleTec Ghana’s inability to implement salary increment for over a year now.An agitated call centre employee, who spoke to Myjoyonline.com on condition of anonymity, said the company was cheating the workers and that "For about two years no salary increment, nothing. We are like slaves.”The source said the about 350 employees of the centre have laid down their ‘tools’ pending a meeting between the workers’ union and the management of the company.Abdul Gafaru, a Trustee of the TeleTec Ghana workers confirmed the strike action in an interview with Myjoyonline.com.Abdul said the workers are "really just pissed off" with their working conditions and salaries.He noted that they have been compelled to embark on the sit-down strike due to company’s persistent refusal to address their concerns and will only go back to work depending on the outcome of a meeting with employers.The trustee disclosed that the call centre operators of Vodafone are the least paid in the sector with a degree holder taking home GHS370 a month. There are deductions to this amount if a staff is absent from work for even a day.A worker of similar standing at other telecom operators, he said, take home above GHS600.Abdul said they have been taken for granted for far too long although they have adhered to the Collective Bargaining Agreement of the Communications Union of the Trade Union Congress (TUC).They are willing to sit down with management on the way forward but until then, they are not resuming work, he added.
